An elevator is a permanent transportation device serving a number of specific floors within a building, the car of which runs in at least two columns of rigid rail movements perpendicular to the horizontal plane or inclined at an angle of less than 15 ° to the plumb line, the elevator comprising a car, a traction system, a door system, an electrical control system and a safety protection system.
The door system comprises landing doors and car doors, is the only portal for passengers to enter and exit the elevator, and is also a necessary protective device for passengers to take the elevator. According to the structure of the elevator, the car door is arranged on the side face of the car and moves up and down along with the car, and the car door is used for closing the car and protecting passengers in the car. The landing door is arranged at the floor where each car stays, the landing door is fixed, and the number of the landing doors is set according to the number of floors where the car stays. In this way, during normal operation of the elevator, the car passes only for other landing doors except for the position where the car needs to stay.
In order to open the landing door simultaneously when the car is opened, a mechanism which can be opened simultaneously by the car door and the landing door is needed, at present, the car door and the landing door are opened by adopting a mechanism called a door knife, the door knife is arranged on the car, the door lock roller is arranged on the landing door, and when the landing door is needed to be opened simultaneously, the door knife clamps the door lock roller, so that the moving distance of the door lock roller exceeds the unlocking stroke, and the landing door is opened. When the landing door is not required to be opened, the door lock roller passes through the door knife, friction is generated between the door lock roller and the door knife due to the structural reasons of the door knife and the door lock roller, and sound is generated every time the elevator passes through the landing door.
But not linkage between current sedan-chair door and the layer door, the sedan-chair door has the opening mechanism of self, and the opening mechanism of sedan-chair door can't drive the layer door and open, and the opening of layer door is another set opening mechanism, and the opening of layer door just can be opened by layer door opening mechanism owing to the sedan-chair is to the layer, and the opening of layer door is with the sedan-chair linkage, not with the sedan-chair door linkage, consequently when the sedan-chair stopped the position error appears, can appear that the sedan-chair door opens and the layer door can't open the situation.
